Interfacial adhesion article and method

Abstract

An article is provided. The article includes an acrylate layer; a substrate overlaying the acrylate layer; and an adhesive layer between the acrylate layer and the substrate, wherein the adhesive layer includes germanium; wherein a release value between the acrylate layer and the adhesive layer is more than 200 g/inch.

What is claimed is: 
     
       1. An article comprising:
 an acrylate layer, wherein the acrylate layer is a non-adhesive film; 
 a substrate overlaying the acrylate layer; and 
 an adhesive layer between the acrylate layer and the substrate, wherein the adhesive layer comprises germanium; 
 wherein a release value between the acrylate layer and the adhesive layer is more than 200 g/inch. 
 
     
     
       2. The article of  claim 1 , wherein the release value between the acrylate layer and the adhesive layer is more than 400 g/inch. 
     
     
       3. The article of  claim 1 , wherein the release value between the acrylate layer and the adhesive layer is more than 500 g/inch. 
     
     
       4. The article of  claim 1 , wherein the thickness of the adhesive layer is less than 10 nm. 
     
     
       5. The article of  claim 1 , wherein more than 90% of the adhesive layer is germanium. 
     
     
       6. The article of  claim 1 , wherein more than 95% of the adhesive layer is germanium. 
     
     
       7. The article of  claim 1 , wherein the substrate comprises a metal layer. 
     
     
       8. The article of  claim 7 , wherein the metal layer comprises at least one selected from the group consisting of individual metals, two or more metals as mixtures, inter-metallics or alloys, metal oxides, metal and mixed metal oxides, metal and mixed metal fluorides, metal and mixed metal nitrides, metal and mixed metal carbides, metal and mixed metal carbonitrides, metal and mixed metal oxynitrides, metal and mixed metal borides, metal and mixed metal oxy borides, metal and mixed metal silicides, and combinations thereof. 
     
     
       9. The article of  claim 1 , wherein the substrate comprises a polymeric film. 
     
     
       10. The article of  claim 9 , wherein the polymeric film is selected from polyolefins, halogenated polyolefins, polyamides, polystyrenes, nylon, polyesters, polyester copolymers, polyurethanes, polysulfones, styrene-maleic anhydride copolymers, styrene-acrylonitrile copolymers, ionomers based on sodium or zinc salts or ethylene methacrylic acid, polymethyl methacrylates, cellulosics, acrylic polymers and copolymers, polycarbonates, polyacrylonitriles ethylene-vinyl acetate copolymers, and fluoropolymers. 
     
     
       11. The article of  claim 1 , further comprising a metal layer, wherein the adhesive layer is in between the metal layer and the acrylate layer. 
     
     
       12. The article of  claim 11 , further comprising a second adhesive layer between the metal layer and the substrate, wherein the second adhesive layer comprises germanium. 
     
     
       13. A method comprising:
 providing a substrate; 
 applying an adhesive layer on the substrate, wherein the adhesive layer comprises germanium; and 
 applying an acrylate layer on the adhesive layer, wherein the acrylate layer is a non-adhesive film; 
 wherein a release value between the release layer and the acrylate layer is more than 200 g/inch. 
 
     
     
       14. The article of  claim 1 , wherein the adhesive layer is in direct contact with the acrylate layer.
